Abstract: Apparatus for generating hydrogen by the electrolytic dissociation of water comprises an electrolytic cell (C) having a cathode (13) and an anode (12) separated by an electrolyte (14), an electrical power supply connected to the cell for applying a voltage across the cathode and anode, a water reservoir (1),(2) connected to the cell for supplying water to the anode side of the electrolytic cell, a hydrogen-water separator (21) connected to the cell for receiving hydrogen and water from the cathode side of the cell and separating the hydrogen from the water, and a water return line (25) connecting the hydrogen-water separator to the water reservoir for returning water from the separator to the water reservoir whereby the water is recycled to the anode side of the cell. A float valve in the upper region of the hydrogen-­water separator closes the hydrogen outlet (30) in response to an increase in the water level in the separator to the level of the hydrogen outlet, so as to prevent water from entering the hydrogen outlet in the event of a malfunction. A pressure relief valve (210) in the hydrogen-water separator discharges hydrogen from the separator to the atmosphere in response to an increase in the gas pressure in the separator beyond a predetermined level. A sensor (3) in the water reservoir produces an electrical signal in response to a drop in the water level in the reservoir to a predetermined level, or in response to a predetermined change in the electrical conductivity of the water, and control circuitry responds to the electrical signal for interrupting the supply of electrical power to the cell.

Abstract: A method of extracting particulate matter from waste material produced by peeling vegetable products, especially for extracting starch from waste material produced in peeling root vegetables. The waste material including the particulate material is by means of a liquid supplied to a moving filter belt (10) from which liquid containing particulate matter is sucked away. Liquid containing a high percentage of particulate matter and sucked away from the filter belt is recirculated to the filter belt at a location thereof which in the direction of movement of the belt is positioned after the point of the belt where the waste material from the peeling machine is supplied. Thereby, the waste material forms at the filter belt a filter cake for filtering the recirculated liquid containing particulate matter. The invention also relates to a device for extracting particulate matter from waste material produced in peeling vegetable products.

Abstract: A non-intrusive fluid level detector including a single point capacitive sensor (C4) mounted on the outside surface of a receptacle (10) such that capacitive principles can be utilized to sense the level (1, 2) of a liquid contained within the receptacle (10). The sensor assembly is disposed in a substantially fixed position on the exterior wall of the receptacle (10) wherein the dielectric effect of the liquid changes the effective capacitance of the sensing capacitor (C4) as the liquid rises and falls within the receptacle (10). This change in effective capacitance is detected by electronic circuitry included in the detector device. In one embodiment, the fluid level detector is directly mounted to a completely non-conductive receptacle (10). In another embodiment, the fluid level detector is mounted to a non-conductive window (12) which is an integral part of a receptacle fabricated out of a conductive material.

Abstract: A method of and an apparatus for automataically determining the stem content of leaf tobacco from a preselected sample of the tobacco including lamina and stem is disclosed. The apparatus utilizes a dryer, such as a fluidized bed dryer (20) or a rotary drum dryer (110) with internal vanes, for applying heat to remove moisture and volatile organic compounds from the sample while concurrently agitating it for a period of time sufficient for preliminary reduction of the sample into a mixture of at least partly segregated lamina and stem portions. The mixture is then introduced into a separator (33; 180) for further agitation thereof to remove remaining lamina from the stem portions. The resulting stem portions are classified into at least two categories according to a thickness dimension of the stems. The stems in each category are weighed and compared with the weight of the tobacco sample to determine the stem content of the sample. This information is used to regulate the processing of the tobacco from the bale or of the same grade to maintain a desired amount of stem in each category in the final smoking article being produced. The separator (33;180) includes a container having a wall (37; 190, 192) which is vibratable to cause movement of a plurality of elastomeric balls (47) against the tobacco mixture to thresh the remaining lamina from the stem portions, after which the lamina is discarded. In one embodiment, the stem portions are transferred to a grader (60) which aligns the stem portions and feeds them along preset paths having apertures for   discharging stems of less than a predetermined thickness for weighing. After weighing those stem fractions, the width of the apertures is selectively increased to discharge the remaining stems of greater thickness from the grader. In another embodiment, the stems are graded into two sizes by the vibratory separator (180) and are weighed and discharged as in the first embodiment.

A curved endwall (15) of the ditch provides a common curved top outer peripheral wall of the thickener well. The remainder of the well has a cylindrical configuration integral with the orbital ditch bottom (29) and extending downwardly therefrom to a position below the horizontal plane of the ditch bottom. A sludge raking structure (28) is positioned at the bottom of the well for periodically raking settled sludge into a sludge outlet (36) at the bottom of the well. A surface aerator (20) is provided between and spaced from the other ditch endwall (14) and a juxtaposed end of the partition (19) or other aeration apparatus mounted in a channel(s) to aerate and propel a liquid-solids sludge mixture wasted from a secondary treatment apparatus and fed into the orbital ditch. The mixture is circulated in the ditch and across and through a top portion of the well. The orbital ditch (10) may be decanted by turning off the aerator (20), allowing a clear liquid top layer to form in the ditch and decanting the clear liquid from the tank by lowering a weir (46) or by adding additional activated sludge to the ditch to displace clear liquid over a fixed weir.
